Error code
(decimal)
The process alarm upper/lower limit value at any of the
buffer memory addresses 86 to 117 (Un\G86 to Un\G117)
33
is outside the -65536 to 65535 range.
indicates the channel number set incorrectly.
The rate alarm upper/lower limit value at any of the buffer
memory addresses 122 to 137 (Un\G122 to Un\G137) is
34
outside the -65536 to 65535 range.
indicates the channel number set incorrectly.
The A/D conversion starting time setting at any of the
buffer memory addresses 5, 6 (Un\G5, Un\G6) is outside
2
35
the 0 to 32767 range.
indicates the channel number set incorrectly.
The offset value is equal to or greater than the gain value
40 at the time of user range setting or user range restoration.
indicates the error causing channel number.
The offset/gain channels were set at the same time during
500
offset and gain value settings, or both were set to 0.
The process alarm upper/lower limit values at the buffer
memory addresses 86 to 117 (Un\G86 to Un\G117) are set
contradictorily.
indicates the channel number set incorrectly.
6
indicates the following state.
2: Lower lower limit value > lower upper limit value
3: Lower upper limit value > upper lower limit value
4: Upper lower limit value > upper upper limit value
The rate alarm warning detection period at any of the
buffer memory addresses 118 to 121 (Un\G118 to
70
Un\G121) is outside the 10 to 5000ms range.
indicates the channel number set incorrectly.
After the rate alarm warning detection period at any of the
buffer memory addresses 118 to 121 (Un\G118 to
Un\G121) has been changed, the new rate alarm warning
71
detection period is not a multiple of the corresponding time
or count averaging conversion period.
indicates the channel number set incorrectly.
After the time or count averaging setting at any of the
buffer memory addresses 1 to 4 (Un\G1 to Un\G4) has
been changed, the rate alarm warning detection period is
72
not a multiple of the corresponding new time or count
averaging conversion period.
indicates the channel number set incorrectly.
The input signal error detection setting value at any of the
buffer memory addresses 138 to 141 (Un\G138 to
80
Un\G141) is outside the 0 to 250 range.
indicates the channel number set incorrectly.

MELSEC-Q
Processing
Re-set the process alarm upper/lower limit
value to within -65536 to 65535.
Re-set the rate alarm upper/lower limit value
to within -65536 to 65535.
Re-set the A/D conversion starting time
setting to within 0 to 32767.
Reset so that the offset value becomes
smaller than the gain value.
Reset the contents of buffer memory
addresses 22 and 23 (Un\G22 and Un\G23).
Re-set the contents of the buffer memory
addresses 86 to 117 (Un\G86 to Un\G117).
Re-set the rate alarm warning detection
period to within 10 to 5000ms.
Re-set the rate alarm warning detection
period so that it is a multiple of the time or
count averaging conversion period.
Re-set the time averaging or count
averaging setting so that the corresponding
rate alarm warning detection period is a
multiple of the time or count averaging
conversion period.
Re-set the input signal error detection
setting value to within 0 to 250.
